scala - Invoke 2 REST services on Playframework to compose a response -

i having problem webservice invoking on playframework. have example invoke 1 service , use response route

def test = action.async { implicit request =>     val baseurl = "serviceurl"      ws.url(baseurl).get().map { response =>       val result = response.json.asopt[list[person]]        ok(views.html.test(result.get))     } } 

this works fine, want invoke 2 webservices, can't compose response because ws.url().get() calls return future , don't know how extract option inside of it. question is:

how option inside future?

i tried doing this:

def test = action.async { implicit request =>     val baseurl = "serviceurl"      val wsresult = ws.url(baseurl).get().map { response =>       val result = response.json.asopt[list[person]]     }      ok(views.html.test(wsresult.get)) } 

but said wsresult has instance of future , not option

you can call second webservice inside map block of first webservice , change map flatmap in first service call.

val wsresult = ws.url(baseurl).get().flatmap { response =>       val result = response.json.asopt[list[person]]      secondwebserice.map{ res=>      ok(views.html.test(result.get))  } } 

since question, guess, 2 web services independent, can use comprehension

val wsresult1 = ws.url(baseurl).get().map { response =>       val result = response.json.asopt[list[person]]     } val wsresult2 = ws.url(baseurl2).get().map { response =>       val result = response.json.asopt[list[person]]     }  val result = { r1<-wsresult1  r2<-wsresult2  }yield(r1.get++r2.get)  result .map {res=>  ok(views.html.test(res)) }
